Yeah, an old TV rotator could do it. Or a ham antenna rotator, those
are much more heavy duty.

What about those old systems for aiming antennas on tripods from your
living room?
Is there anything like that remotely controlled that you could rig
up?

Hmm...maybe it doesn't need two radios, but two antennas. Like
a
spatial diversity setup.
I wonder if McCown makes parts for that.

May not be a viable solution with an 11 ghz backhaul, but you
could install two radios, once that is on target in summer and
one
in winter, and switch between them without climbing at least.

When you look at the high voltage distribution lines with

twisting then doesn't do anything but put tension or

actually
start to lean, the cross bracing stays pretty much
immobile.. But putting two poles up pretty much brings it
to
the price of a tower.

Looking at a photo of this pole, it has a noticeable
curvature near the top. Maybe we'll move the dish below
the curve and see if that helps.

For us they are and haven't hand problems with
twisting. We've got one with a link that's been
steady for 6 years or more. The problem is
accessing
the link on short notice since we don't know a
bucket
truck and operators are very busy. It seems like
you
could put two wood posts on either side of the pole
and secure a 4x4 with large lag screws to keep it
from
twisting.

I always thought wood poles would be great for

locations but now maybe not.

I've got a 70' (61' AGL) class 3 pole with
an
AP and backhaul on it. It's
been in the ground about 3 years now.
This past spring we noticed the signal drop
slowly on the backhaul over the
course of a month. A climber went up and
adjusted it by about 9 degrees,
but he said the mount was tight when he got
there. This past month the RSSI
on the backhaul has been slowly dropping
again.
The humidity here tends to shoot way up in
the
summer and drop in the
winter. I'm supposing this beast must be
twisting as it soaks up moisture
and then dries out again.
Is this a problem that might diminish as
the
pole ages, or is there perhaps
any possible remediation? I guess the
permanent fix is a real tower or a
steel pole, but I guess I'm hoping that one
of
you old phone guys knows some
magic trick. Seems like if there was a wire
attached to this pole, that a 9
degree twist would put some wicked tension
on
it.
